A jewelry enhancer is provided which may repurpose items of jewelry, display items of jewelry and be worn as an adornment. The jewelry enhancer includes a plurality of hinged rings, capable of opening, closing and securing multiple strands of string jewelry therethrough. The jewelry enhancer further includes a button-clip that can secure and display shank buttons, a bar pin cap able of affixing the jewelry enhancer to garments, a jewelry bale cap able of attaching the jewelry enhancer to items of string jewelry and a brooch bar capable of eclipsing the button-clip for a fashionable effect.

A wearing member includes: a strap part including a first portion and a second portion extending from the first portion, and a fastening part slidable along the first portion. The first portion extends from one end thereof and passes through the fastening part, and the other end of the first portion is connected to the second portion. The second portion includes one end extending from the first portion, and the other end coupled with the fastening part. The fastening part includes a cover including a magnet, and a fastening part lower member. In a first state, the magnet is spaced apart from the first portion, and the fastening part is slidable from the first portion. In a second state, the first portion is in contact with the magnet, and the fastening part is fixed to the first portion.

Provided are an electronic device and a wearable device. In the electronic device, a contact surface is provided on an outer surface of a housing; an accommodating space is formed inside the housing; a connecting head is provided on the housing and is used for electrical connection to a power source to transmit electric energy for the electronic device. A first electrode and a second electrode are provided on the contact surface at intervals and are used as measuring electrodes of an ECG signal detection circuit; each of the first and second electrodes is electrically connected to the connecting head; and a mainboard is electrically connected to the connecting head and is used for obtaining ECG parameters according to ECG signals acquired by the first electrode and second electrode.

A link bracelet includes two rows of side links forming the edges of the bracelet and at least one row of central links arranged between the side links, wherein the side links each include at least two through holes in the inner face thereof facing the central links and the central links are traversed by at least two housings. The bracelet includes arbors inserted into each of the holes in the side links, the head of the arbors being fitted into the housings of the central links and each having a grooved portion in proximity to the end thereof, and the central links include an opening giving access to the grooved portions, which are arranged to cooperate with a locking member designed to be inserted into the openings in the central links to maintain the assembly of the bracelet.
